DRIVING CONNECTION FOR MAGNETOS.

Specification of Letters Patent.

Patented Mar. 13, 1917.

0 all whom it may concern:

lie it known that l, Louis lV. lvrrmr, a

citizen of the United States of America, and a resident of \Vaterloo,Blackhawk county, Iowa, have invented certain new and usefulimprovements in Driving Connections for Magnctos, of which the followingis a spccification. 1 i Y My invention relates to improvements indriving-conncctions for magnetos. and particularly for those employed incombination with electric ignitcrs of internalarmnblistion engines, andthe. object of my improvement is to furnish means for adjustably settingand securing the connection between the driving-means and the magneto sothat the magneto may beset to actuate thci niter at a. desired time.

This object I have accomplished by the means which arehereinafterdescribed and i claimed, and which are illustrated in theaccompanymg drawings, in winch:

Figure 1 is .a side elevation of a magneto and my improved ad ustabledriving-conncctlon therefor as connected to drivingmeans, parts of eachbeing in partial seca magneto, having a driven-shaft 2 alined. with adriving-shaft 16 adapted to be to: tated by means not'shown. The'maguctois adapted to be installed on an internal-combustion engine incircuit-with the ignite: thereof and set to break the circuit in theusual lnanner. The, driring-conncctions between the two shafts 2 and 16are of the univcrsal-coupliug type and can be set at any angle desiredto permit the n'lagneto to 00-;

operate with the igniter as maybe desired.

The drimug-connection comprises the following parts, as opcrativelyassociated with each other and with the said drivingand driven-sha fts:

The end of the shaft- 2 is diminished to seat a coupling-sleeve 4 atlthand has oppositely-located grooves to seat lugs 3 on said sleeve. Theopposite face of the sleeve 4 is transversely troughed at at rightangles to the grooves on said shaft Tlle numeral 13 denotes a disksplined on the diminished end 15 of the driving-shaft ll), conccntrically. and ha ring on its left-hand face alow raised central boss 14. Ashallow concave circular plate- 8 is fitted rotatably over and upon theboss 11-, and has a raised central part 7 of rehil'ively small diameter,which latter has a pressed-out transverse diametral ridge 6. This ridge6 is fitted slidingly in the end-grooves 5 of the sleeve 4, whereby thedriving-shaft 16 may still rotate the driven-shaft 2, although theshafts may be out of alinement.

l have supplied the following-described novel means for adjustahlvsecuring the plate 8 upon the boss ll of said disk 13. The numeral 9denotes a flat rectangular clamgiugancmher having one end bent to one sie at 11. and having at its opposite longitudinal edges the rectangularparts or spacers 17 bent in the same direction as the part 11, the partsor spacers 11 and 11' contacting with the face of the disk 13 justwithout the boss H to permit the other flat end of the member to overlieand contact with thc'adjacent face of said boss. The. member 9 isorificcd at 18. in line with a screw hole in the disk .13. and a screw10 is passed through said alined orifices; to clamp the plate 8 tightlyin frictional engagement with the boss 14. Two of theseclan'ipiug-devices are used, oppositely, and it is merely necessary toloosen the screws to permit the plate 8 to be turned sulliciently beforebeing I'G-SBGIIECI, to place the connected parts of the magneto in aproper angular relation to the movable parts of the igniter, relative toadvancing or retarding the ignition (if the fuel in thecomlmstionchambcr of the engine. It will be observed that the adjustmentis'perfect, and that the parts are so accessible as to render theadjustment easy, wherever "the. magneto is located.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is:

A driving-connection for a magneto, comprising in combination with adriven-shaft of a magneto and a driving-shaft, a clutchmember coupled tosaid driven-shaft, said clutch-member. having an annular concave coaxialdisk-part. a disk fixed on and coaxial tinned diskmrt to hold thefirst-mentioned with the drivingfihafl of larger diameter disk-part inadjustable frictional drivinglhan the iirst-im-ntimled disk-part andhavengagement with the other disk-part.

and means for relensubiy securing said G. (J. KENNEDY, 10 clampseon'ipressibly upon the first-men- PEARL STANTON.
